Respuesta :
You have to add 1 1/4 + 1 3/4. Since they have common denominators you can just add all the numbers, 1+1=2, 1+3=4 since 4/4 is equal to one, you would add a one to the 2, so the answer would be 3. So Ed spent 3 hours doing homework during the weekend.
Answer:
3 hours
Step-by-step explanation:
We have that,
Time spent by Ed to do math homework = [tex]1\frac{1}{4}[/tex] = [tex]\frac{5}{4}[/tex] hours.
Time spent by Ed to do science homework = [tex]1\frac{3}{4}[/tex] = [tex]\frac{7}{4}[/tex] hours.
Thus, total time spent by Ed = Time for math + Time for science
i.e. Total time spent by Ed = [tex]\frac{5}{4}[/tex] + [tex]\frac{7}{4}[/tex]
i.e. Total time spent by Ed = [tex]\frac{12}{4}[/tex]
i.e. Total time spent by Ed = 3 hours.
Hence, the time spent by Ed doing his homework is 3 hours.
